Why is it critical to monitor patients closely after arterial puncture?

Monitoring patients closely after an arterial puncture is critical primarily to detect complications immediately. After such a procedure, there are several potential risks, including bleeding, hematoma formation, and arterial spasm. If any of these complications occur, it is essential for healthcare providers to identify them promptly in order to take appropriate action, which could include applying pressure to control bleeding or administering additional treatments to address any arising issues. Immediate detection of complications can greatly influence patient outcomes, making vigilant monitoring a key responsibility of healthcare professionals after performing an arterial puncture.

While ensuring patients remain calm, providing quick results, and preparing for discharge are all important aspects of patient care, they do not take precedence over the need to monitor for complications that could arise during or after the procedure.
